    INDUSTRY FOCUS

    Fasteners for Infrastructure & Civil Engineering

    Anchor bolts and structural fasteners for bridges, transport networks, water infrastructure, and heavy civil construction. Full traceability and structural compliance.

    OVERVIEW

    Reliable Bolting for Long-Life Infrastructure

    Public infrastructure projects demand fasteners with proven long-term reliability, complete traceability, and compliance with structural engineering standards. Bridges, transport networks, water treatment facilities, and marine structures all require bolted connections that will perform for decades.

    We supply anchor bolts, structural bolting assemblies, and specialty fasteners for civil engineering applications. Our products meet ASTM F1554, AS/NZS 1252, EN 14399, and other relevant standards, with full certification documentation for audit and compliance purposes.

    From foundation anchor bolts to structural steelwork connections, we support civil contractors and engineers with material selection, certification, and reliable supply for projects of all scales.

    EMG supplies ASTM F1554 anchor bolts in Grade 36, 55, and 105 — along with AS/NZS 1252 structural bolting assemblies — with hot-dip galvanizing and full EN 10204 3.1 certification for infrastructure projects with 50+ year design lives.

    Where Our Fasteners Are Installed

    A closer look at the key sectors within infrastructure & civil engineering where our fasteners play a critical role in equipment integrity and safety.

    Bridges & Structural Steelwork

    Bridge and structural steel connections require high-strength friction grip bolting with proven long-term performance. Fasteners must resist fatigue from dynamic loading, atmospheric corrosion, and the thermal expansion cycles experienced over 50+ year design lives.

    Key Equipment
    • Steel girder and truss connections
    • Bearing assemblies and expansion joints
    • Cable anchorage and stay systems
    • Guard rail and barrier fixings
    • Structural steelwork splices and moment connections

    Water & Wastewater Infrastructure

    Water treatment, desalination, and wastewater facilities expose fasteners to chlorinated water, brackish environments, and chemical dosing systems. Stainless steel and duplex grades are essential for corrosion resistance and hygienic compliance.

    Key Equipment
    • Filter vessels and clarifiers
    • Pump stations and valve assemblies
    • Desalination reverse osmosis frames
    • Chemical dosing and storage systems
    • Pipeline flanges and penstock connections

    Transport & Energy Infrastructure

    Rail networks, ports, tunnels, and energy transmission structures demand fasteners that perform reliably under vibration, dynamic loads, and outdoor exposure. Hot-dip galvanised and stainless steel grades ensure durability in exposed environments.

    Key Equipment
    • Rail viaducts and station structures
    • Tunnel lining and ventilation systems
    • Port cranes and wharf structures
    • Transmission tower and substation bolting
    • Wind turbine and solar farm foundations

    FREQUENTLY ASKED QUESTIONS

    Technical FAQs

    What ASTM F1554 grade should I use for anchor bolts?

    +
    ASTM F1554 Grade 36 (250 MPa yield) is suitable for general-purpose anchoring. Grade 55 (380 MPa yield) is used where higher strength is needed with weldability maintained. Grade 105 (724 MPa yield) provides the highest strength for heavy structural connections but is not weldable. Grade selection depends on the design loads and whether field welding is required.

    Can anchor bolts be hot-dip galvanized?

    +
    Yes. Anchor bolts in F1554 Grade 36 and 55 are routinely hot-dip galvanized per ASTM A153 or A123. Grade 105 anchor bolts can be galvanized but require careful process control due to their higher hardness — ASTM F2329 provides specific requirements for galvanizing F1554 Grade 105 anchor bolts to prevent hydrogen embrittlement.

    What fasteners are used in water treatment and desalination plants?

    +
    Water treatment facilities typically require stainless steel (316L) or Duplex 2205 fasteners for corrosion resistance in chlorinated and brackish water environments. For structural connections, hot-dip galvanized carbon steel is standard. Desalination plants handling high-salinity water often specify Super Duplex or nickel alloy fasteners for critical process connections.
